Phylctic Parallelism in Metamorphic Species. 439 



and if this were interpolated between the Salyrida 

 and NympluilicUC) such an arrangement could only 

 be based on the larval structure, and that of the 

 imagines would thus remain unconsidered, since 

 no other common characters can be found for these 

 two genera than those which they possess in 

 common with the other Nymphalideous genera. 



The emperor-butterflies (Apaturd], by the ocelli 

 of their fore-wings certainly put us somewhat in 

 mind of the Satyrinte, in which such spots are 

 always present ; but this character does not occur 

 in the genus Nymphalis, and is likewise absent in 

 most of the other genera of this group. The 

 genus Apaiura shows in addition a most striking 

 similarity in the markings of the wings to the 

 purely Nymphalideous genus Limcnitis, and it is 

 therefore placed, by those systematists who leave 

 this genus in the same family, in the closest 

 proximity to Limenitis. This resemblance cannot 

 depend upon mimicry, since not only one or 

 another but all the species of the two genera 

 possess a similar marking ; and further, because 

 similarity of marking alone does not constitute 

 mimicry, but a resemblance in colour must also be 

 added. The genus Limenitis actually contains a 

 case of imitation, but in quite another direction ; 

 this will be treated of subsequently. 



It cannot therefore be well denied that in this 

 case the larvae show different relationships to the 

 imagines.
